molecular characterization of a tem-21 beta-lactamase in a clinical isolate of morganella morganii.a clinical isolate of morganella morganii, with reduced susceptibility to expanded-spectrum cephalosporins and aztreonam, was found to produce an extended-spectrum beta-lactamase with a pi of 6.4. the nucleotide sequence of the encoding gene was that of the gene encoding tem-21. this is the first molecular characterization of an extended-spectrum beta-lactamase in m. morganii.19989687421
important and emerging beta-lactamase-mediated resistances in hospital-based pathogens: the amp c enzymes.resistance to third-generation cephalosporins mediated by beta-lactamases is an increasing problem for clinical therapeutics. a wide range of enterobacteriaceae produce these ampc enzymes (bush-jacoby-medeiros group 1), including enterobacter spp., citrobacter freundii, morganella morganii, providencia spp., and serratia marcescens. resistance via this mechanism has been shown to be statistically correlated with the use of some third-generation cephalosporins, and the infections caused by these ...19989635237

[clinical and laboratory significance of inducible beta-lactamases].many species of bacteria have inducible expression of beta-lactamase and the enzyme production in these bacteria is normally held at a low level by a repressor mechanism, but in the presence of a beta-lactamase inducer this repression is lifted and enzyme production is greatly increased. inducible synthesis of beta-lactamase was first described for the gram-positive organism bacillus licheniformis. after that inducible expression of beta-lactamase was discovered in gram-negative bacteria like en ...19958643019
the changing nature of aminoglycoside resistance mechanisms and the role of isepamicin--a new broad-spectrum aminoglycoside. the aminoglycoside resistance study groups.aminoglycoside resistance mechanisms from recent studies were compared with those found in earlier studies in the usa and europe for three pathogen groups. among citrobacter-enterobacter-klebsiella, four single mechanisms (aac(3)-ii, aac(3)-i, ant(2")-i and aac(6')-i were found in all studies, but the most recent studies showed a significant increase in combinations of aac(6')-i with the other common mechanisms. since aac(6')-i confers resistance to tobramycin, netilmicin and amikacin, combinati ...19958622109
the most frequently occurring aminoglycoside resistance mechanisms--combined results of surveys in eight regions of the world. the aminoglycoside resistance study groups.aminoglycoside-resistant isolates from different patients were collected in 149 hospitals in eight regions of the world. aminoglycoside resistance mechanisms were determined in 11,079 of these isolates by the correlation of resistance phenotypes to 12 aminoglycosides and dna hybridisation with up to 19 resistance genes. a very large diversity of different resistance mechanisms was found. for example, in escherichia-morganella-proteus-salmonella-shigella, at total of 53 different mechanisms was f ...19958622108
turkey rhinotracheitis virus isolated from broiler chicken with swollen head syndrome in japan.turkey rhinotracheitis (trt) virus was first isolated from a commercial broiler chicken with swollen head syndrome (shs) in japan. at the same time, newcastle disease virus (ndv), infectious bronchitis virus (ibv), avian reovirus (arv), escherichia coli (e.coli), morganella morganii, and proteus mirabilis were also isolated from the same broiler chicken. the presence of antibodies to trt virus was confirmed in the sera of 34-day-old chickens of the flock with shs, however the antibodies to trt v ...19958593307
ferric rhizoferrin uptake into morganella morganii: characterization of genes involved in the uptake of a polyhydroxycarboxylate siderophore.iron uptake in morganella morganii, mediated by the fungal siderophore rhizoferrin, was studied. a mud1 insertion mutant devoid of growth on ferric rhizoferrin was complemented by a chromosomal dna fragment of m. morganii that encoded an outer membrane protein and a periplasmic protein named ruma and rumb (for rhizoferrin uptake into morganella spp.), respectively. ruma and rumb have the same transcription polarity and are probably cotranscribed from an iron-regulated promoter upstream of ruma. ...19968550472

alpha-keto acids are novel siderophores in the genera proteus, providencia, and morganella and are produced by amino acid deaminases.growth promotion and iron transport studies revealed that certain alpha-keto acids generated by amino acid deaminases, by enterobacteria of the proteus-providencia-morganella group (of the tribe proteeae), show significant siderophore activity. their iron-binding properties were confirmed by the chrome azurol s assay and uv spectra. these compounds form ligand-to-metal charge transfer bands in the range of 400 to 500 nm. additional absorption bands of the enolized ligands at 500 to 700 nm are re ...19938478334
determinants of the activity of beta-lactamase inhibitor combinations.inhibitor combinations provide one strategy to overcome beta-lactamase-mediated resistance. their success depends, obviously, on the inhibitor being able to bind and inactivate the beta-lactamase molecules. clavulanate, sulbactam and tazobactam are irreversible inactivators of many beta-lactamases, forming covalent complexes which resist hydrolysis. 'suicide' kinetics are seen with some, but not all, enzymes. all three compounds inactivate staphylococcal penicillinase, the chromosomal beta-lacta ...19938449836
t lymphocyte responses to antigens of gram-negative bacteria in pyelonephritis.we showed previously that large numbers of t lymphocytes accumulate within a few days in the kidneys of rats with ascending pyelonephritis induced with escherichia coli or pseudomonas aeruginosa. cd4+ t cells propagated from the lesions exhibited mhc-restricted proliferative responses to formalin-fixed bacteria of the species used to induce infection. in the present study we investigated further the nature of the antigens responsible for the t cell proliferation and studied the ability of differ ...19938403542
